[PATCH] x86/kaslr: Fix build warning in KASLR code in boot stub

From: Kirill A. Shutemov
Date: Sun Apr 10 2022 - 15:49:28 EST


lib/kaslr.c used by both the main kernel and the boot stub. It includes
<asm/io.h> that intended to be used in the main kernel. It leads to
build warnings like this:

warning: implicit declaration of function 'outl' is invalid in
C99 [-Wimplicit-function-declaration]

Replace <asm/io.h> with <asm/shared/io.h> which is suitable for both
cases.
